natural gas has been an integral part of the modern energy mix for
some time. Due to its great flexibility, it is the ideal complement to
alternative energy sources. gas storage facilities are indispensable
to ensure that natural gas is constantly available everywhere and at
any time, even at short notice. they guarantee the safe and reliable
supply of gas.
storengy Deutschland gmbh is a subsidiary of the French company storengy
s.a., the leading operator of gas storage
facilities in europe. storengy handles the
gas storage activities of the gDF sueZ
group, one of the world’s major energy
companies.
Decades of experience in the construction
and operation of underground gas storage
facilities and 23 gas storage sites currently
situated in european core markets consolidate our top position in the planning, development, construction, and reliable and
safe operation of gas storage systems.
storengy operates seven storage facilities
and a working gas volume total of 2 bn m3
in germany, making it one of the largest
storage operators in this key market. ongoing expansion of our storage facilities will
further increase the working gas volume
and injection and withdrawal capacities in
germany over the next few years.
We operate four pore storage and three
cavern storage facilities within two of
the german market areas. the favourable
geographical spread of our sites allows
for a swift reaction to a broad range of storage requests, offering our customers the
desired flexibility. storengy is your number
one partner for natural gas storage as it
is well-integrated into the gas market
and offers a range of innovative products.

Short-Term Flexibility – Long-Term Reliability
Our types of
storage facility
The primary component of natural gas
is methane, the smallest hydrocarbon. It
is formed during the decomposition of organic compounds. With the sinking underground of soil deposits containing a large
proportion of organic substances as sediment, the rise in pressure and temperature causes the methane to be released.
In favourable conditions, the natural gas
Cavern storage facilities, on the other hand,
are cavities in underground salt ­formations,
man-made by means of leaching. As to
size, these can be as large as 50 metres in
diameter, 300 metres in height, with a total
volume of around 70 million cubic ­metres.
They do not, however, usually lie so deep
in the ground. Due to their large diameter wells, salt caverns are able to supply

cumulates in porous rock in natural traps
within the earth’s crust to form reservoirs.
Following the complete clearance of the
gaseous content, these reservoirs can
then be developed for use as gas storage
facilities, providing a suitable location and
requisite reservoir parameters.
Pore storage facilities can be developed
from water-filled structures – so-called
­aquifers – as well as from depleted natural
gas or crude oil fields.

These aquifers are usually of substantial size and are mostly used for long-term
storage. Typically, they are filled during
the summer and provide the stored gas

large quantities of stored gas within a short
space of time. They are particularly useful
in supplying flexibility at times of peak demand and for optimising market situations.
Natural gas storage facilities contain a specific quantity of gas known as cushion gas,
which ensures adequate pressure and acts
as a stability reserve. The remaining capacity of the reservoir is then available for storing the usable working gas.
Storengy, with its four high-performance
pore storage and three cavern storage facilities in Northern and Southern Germany, is excellently positioned in the German
market and can react flexibly to all customer requirements.

more than a third of the total annual energy consumption in germany is used for
heat generation in the housing market.
this explains the pronounced summer versus winter seasonal demand differences.
however, the large gas reserves that supply germany’s demand, whether originating from russia, norway, the netherlands,
or from our own native natural gas reserves, produce gas all year round independently of the seasons. this results
in a large supply during the summer and
potential shortages in the winter. underground gas storage facilities are used
to provide the structural balance required
to cover the extra demand in winter
reliably and independently of external influences. typically, large-volume pore
storage facilities are filled during the summer to provide a reliable source of gas
throughout
the winter.
the emphasis with cavern storage facilities, on the other hand, is on flexibility,
short response times, and high injection
and withdrawal capacities. cavern storage facilities are, therefore, used primarily
for covering short-term peaks in demand.
moreover, they have been increasingly
used in recent years for the purpose of
optimising gas portfolios.

FronhoFen
the Fronhofen h-gas storage facility is situated in southern
germany between Pfullendorf and ravensburg. this storage
facility was established in 1997 in the trigonodus-dolomite of
the former Fronhofen-Illmensee natural gas field. as a seasonal
storage facility, it contributes to load balancing and thus to the
security of supply in the region around stuttgart, the capital of
the german state of baden-Württemberg.
harseFelD
the harsefeld h-gas storage facility is situated 30 km to the
west of hamburg in northern germany. this natural gas storage
facility launched operations in 1992 and comprises two storage caverns mined in the harsefeld salt deposits. With its swift
response times, high-performance compression units and high
withdrawal capacity, harsefeld is perfectly positioned to store
natural gas both flexibly and reliably.
lesum
natural gas in germany falls into two categories differing in fuel
value. lesum is one of only a small number of facilities storing
“l-gas” (slightly lower fuel value), which lends this storage facility
its particular significance. the facility is situated in northern
germany near bremen and started operations in 2001. It possesses two storage caverns within the lesum salt deposit.
Peckensen
the Peckensen h-gas cavern storage facility – situated near
magdeburg in northern germany – has three storage caverns.
these are connected to the two market centres of gaspool
and ncg via the steinitz network connection point. two further
caverns are under construction and are due to be completed in
2012. We start construction in the same year on extension works
planned for the nipkendey site, including two further compression units and additional above-ground plant. moreover, another
pipeline will be constructed in 2012 to improve the capacity of
the connection to the transmission network.
reItbrook
the reitbrook h-gas storage facility is located in northern germany near hamburg. evidence of crude oil and natural gas fields
was first established in 1910, and the crude oil field discovered
later in 1937 at a depth of 600 metres was once the most productive in germany. although crude oil is still extracted today,
part of the former reservoir has been under development for the
purpose of gas storage since 1973. the compression and gas
drying operations are run by e.on. the reitbrook storage facility
with a working gas volume of 350 million cubic metres plays an
important role in balancing demand fluctuations and securing a
reliable supply of natural gas for the city of hamburg.
schmIDhausen
the schmidhausen h-gas storage facility lies 10 kilometres
to the north-west of rosenheim in bavaria, southern germany.
this storage facility was established in a former natural gas
field in 1983. stretching underground over an area of 10 square
kilometres, the tertiary (aquitanian) aquifer lies at a depth of
1,015 metres and is accessible via seven wells. the schmidhausen facility provides seasonal storage opportunities that level
out fluctuations in demand, safeguarding a secure gas supply
to munich, the capital city of bavaria.
uelsen
uelsen h-gas storage facility is located to the north-west of nordhorn in northern germany. It is storengy’s largest pore storage
facility in germany and was established once the uelsen buntsandstein (coloured sandstone) reservoir, discovered in 1964, had
been exhausted. operation of the facility began in 1997 with six
wells and two electrically driven compressor units. the working
gas volume was increased to 750 m cubic metres with the drilling
of a seventh well in 2008. the uelsen site in particular can serve
as an example of the successful and harmonious integration of
an operating plant into its natural environment.
